fable-and-improve

name	fable-and-improve
description	Use when a Claude Code session should let Claude Fable plan and manage the goal, delegate implementation/review/improvement to the Codex design-and-implement workflow, then have Fable verify completion and loop on remaining TODOs.
metadata	{"short-description":"Fable plans, Codex implements, Fable verifies"}

Fable And Improve

Use this skill when the user explicitly wants the fable-and-improve Riela workflow or asks for a Fable-led plan with Codex implementation and review.

Package

• Package id: fable-and-improve
• Workflow id: fable-and-improve
• Parent backend: claude-code-agent
• Parent model: claude-fable-5
• Child workflow: codex-design-and-implement-review-loop
• Required dependency package: codex-design-and-implement-review-loop

This package intentionally provides only a Claude skill. It does not project a Codex or Cursor usage skill.

Install

From a local riela-packages checkout:

riela package install fable-and-improve --source <riela-packages-checkout>/packages/fable-and-improve

User scope:

riela package install fable-and-improve --source <riela-packages-checkout>/packages/fable-and-improve --scope user

Validate

Project scope:

riela workflow validate fable-and-improve
riela workflow inspect fable-and-improve --output json

User scope:

riela workflow validate fable-and-improve --scope user
riela workflow inspect fable-and-improve --scope user --output json

Run

Use a concise workflowInput:

riela workflow run fable-and-improve \
  --variables '{"workflowInput":{"requestedOutcome":"Implement the requested change, review it, and verify completion.","targetScope":"Describe the target files or feature area.","constraints":["Do not modify unrelated files."],"acceptanceCriteria":["The requested behavior works."],"verificationHint":"Run the smallest relevant verification."}}' \
  --output jsonl

For a cheap connectivity check before using Fable, patch the parent Fable nodes to a less expensive Claude Code model:

riela workflow run fable-and-improve \
  --node-patch '{"fable-goal-plan":{"model":"claude-sonnet-4-5"},"codex-implementation-handoff":{"model":"claude-sonnet-4-5"},"codex-implementation-result":{"model":"claude-sonnet-4-5"},"fable-goal-review":{"model":"claude-sonnet-4-5"},"final-output":{"model":"claude-sonnet-4-5"}}' \
  --variables '{"workflowInput":{"requestedOutcome":"Connectivity smoke test only.","targetScope":"No repository changes.","constraints":["Do not edit files."],"acceptanceCriteria":["The workflow starts and delegates correctly."],"verificationHint":"No-op smoke check."}}' \
  --output jsonl

Then run the normal workflow with Fable for a small real task.

Output

Expect the final output to include:

• status
• goalAchieved
• goalMarkdown
• planMarkdown
• delegatedWorkflowRuns
• changedFiles
• verificationEvidence
• reviewEvidence
• commitStatus
• pushStatus
• residualRisks
